>   With <SPAN

   on your local machine, so you will have access to all history and branches
   offline. This is the fastest and most flexible way to develop or test
   patches.

CLASS="PRODUCTNAME"
>Git</SPAN
>, which you can
     get from <A
HREF="http://git-scm.com"
TARGET="_top"
>http://git-scm.com</A
>. Many systems already
     have a recent version of <SPAN

     available in their package distribution system.

CLASS="STEP"
><P
>     To begin using the Git repository, make a clone of the official mirror:

</P><PRE
CLASS="PROGRAMLISTING"
>git clone git://git.postgresql.org/git/postgresql.git</PRE
><P>

     This will copy the full repository to your local machine, so it may take
     a while to complete, especially if you have a slow Internet connection.
     The files will be placed in a new subdirectory <TT
CLASS="FILENAME"
>postgresql</TT
> of
     your current directory.
    </P
><P
>     The Git mirror can also be reached via the HTTP protocol, if for example
     a firewall is blocking access to the Git protocol. Just change the URL
     prefix to <TT
CLASS="LITERAL"
>http</TT
>, as in:

</P><PRE
CLASS="PROGRAMLISTING"
>git clone http://git.postgresql.org/git/postgresql.git</PRE
><P>

     The HTTP protocol is less efficient than the Git protocol, so it will be
     slower to use.
    </P
></LI
><LI
CLASS="STEP"
><P
>     Whenever you want to get the latest updates in the system, <TT
CLASS="COMMAND"

     into the repository, and run:

</P><PRE
CLASS="PROGRAMLISTING"
>git fetch</PRE

    </P

><P
>   <SPAN
CLASS="PRODUCTNAME"
